This invention relates generally to heating radiators and particularly to unitary cabinet-type radiators which may. beset in the wall of a room. 1

l Heretofore radiators have been set in or concealed within the walls of a room by providing separate cabinets or housings within the walls for receiving narrow radiators.

Ordinarily each housing is built into the wall to constitute an air passage having inlet and outlet openings, and the radiator is suspended or mounted within the housing thus constructed.

It is an object of the invention to provide 13 an inset radiator having the housing and the heating unit combined to constitute a unitary structure. A further object of the inv ntion is to rovide a, concealed radiator o compact anti rugged structure, so designed 333 that it wili he sanitar" and easily cleaned.

In accordance with t is invention, a radiating structure is provided having a heating element, preferably a tube of "copper, on which is mounted a cabinet structure made f of a plurality of independent sections. 4 to sections are fastened together in such manner that the entire radiator constitutes a unitary article of manufacture which may be readily installed in a wall. Each section 99 constitu an individual flue having inlet and outlet openings shaped to conform to the air stream to conduct air through the riid-iator and shaped to avoid collecting dirt. The sections are so mounted on the tube that 85 they are heated by conduction from the tube and function as extended surfaces forheating the air that passes throughthem.

The stated objects of the invention, and others that will become apparent upon further consideration of this specification, may be achieved by the apparatus describedherein and shown in the accompanying drawings,

Referring more particularly to the drawings, the radiator constructed in accordance with this invention is adapted to be set in the wall 1 of a room, as shown in Fig. l, with most of its structure concealed from view. When installed in this manner in the Wall, the radiator does not occupy floor space, or other useful space, and it may be adapted to readily conform to the decorative scheme of the room.

The radiator is provided with an air inle. opening 2 that is ordinarily disposed near the floor. In-this particular structure it is shown just above a base-board 3. Air ontering the inlet opening 2 passes upward through the radiator within the wall 1 and returns to the room, after being heated through an outlet opening 4 near the top oi the radiator,

similer in appearance to the inlet opening 2, and disposed, in this instance, for convenience, just below a sill 0t e window. The surface between the inlet opening 2 and the outlet opening 4 constitotes e portion of the wall lthet may be covered by plaster and paper, or other suitelole surface materiel, iii the some manner that the remainder of the well is covered. With the radiator set in the wall in this manner, the only portions exposed to View tore the inlet and outlet openings, and on for controlling the supply of heated fluid the radiator.

The section shown in Fig. 13 is similar to the section of the rediotor shown in Figs. 8, 9 end 10 with the exception that it is recessed. That s, the front plate M is set hook to provide room for applying well covering over it in the manner shown in Fig. l.

The sections and plates may he held in position by shy suitable fixture end the upper end middle runs or" horizontal tuhing 9 pressed through the openings ih'the transverse pistes 15?; end intermediate plates 17. r

The tubes 9 are preferably of drown copper and the upper and middle runs are formed from at single piece of tubing bending it upon itself with the proper degree or curvature to provide parallel horizontsl runs spaced to lit the spaced holes 13 in the transverse plates 12.

The lower run of the tube 9 is o' simple straight piece of tubing which is inserted through the lower openings "1-3 in the sec;

' suitable bend or elbow connection 19 that, as

1 sure to grip the plates an here shown, may be fastened to the tubes by compression couplings 20.

N 0 intermediate plates are provided in the end sections inasmuch as the space is occupied by the tube bends. The ends of the radiator may be closed by suitable end plates 21 that may be pressed into engagement with the edges of the end sections.

After the radiator has been assembled, it may be rigidly locked together by soldering or galvanizing the entire structure, orthe tubes 9 may be expanded b hydraulic pressections carried by them. When thus assembled and locked together, the radiator constitutes a rigid unitary structure which may be mounted in the wall of a room without the necessity of providing any additional casing or housing for receiving it.

As shown in Figs. 2, 6 and 7, the detailed construction of the radiator, shown generally in Fig. 1, is quite similar to that shown in Fig. 8,,with the exception that a larger number of main transverse plates are utilized and the intermediate plates 17 are entirely dispensed with. The heating medium is conducted through horizontal runs of pipes 9 connected together to constitute a continuous passageway in the same manner that the tubes 9 shown in Fig. 8 are connected. On the pipes 9 are mounted a plurality of transverse plates 22 having flanged pipe-receiving openings 13, each of which constitutes 'a partition for dividing the radiator into a plurality of independent flues for convection currents of air. The flanges of the pipe-receiving openings 13 are in heat-conducting contact with the pipes 9 and transmit heat to the transverse plates 22 which, in turn, assist in heating the air in the radiator. v

At the front edge of each transverse plate 22 there is an integrally formed front plate 24 which, in the modification shown in Figs. 1 and 2, is set back or depressed from the plane of the openings 2 and 4 a sufficient distance to permit wall covering such as plaster 23 to be applied across the front of the radiator. Instead of plaster, a decorative metal panel may be used to enclose the front of the radiator, or other suitable cov-' ering may be applied.

As shown, the front plate 24 is shorter than the transverse plate 22 and is disposed at the mid-portion thereof to provide openings above and below it that constitute the air inlet and outlet openings, 2 and 4 re- 25 is disposed parallel with the front plate 24 throughout its mid-portion and is curved forward at its upper and lower portions. The upper and lower ends of the back plate 25 are then turned outward'.to form an S-curve which brings them into the plane of the radiator by means of which the unitary structure may be attached to the wall of a building, as shown in Fig. 2. The curved back late 25 gives a stream-line effect to the air passage through the section and thus provides a path of low resistance for the convection currents.

The section shown in perspective in Fig. 6 is similar to the sections that make up the radiator shown in Figs. 1 and 2, with the exception that thefront plate 24 is not set back. In this modification, the front plate 24 is disposed in the plane of the openings 2 and 4 and occupies the space taken by the wall covering 23 shown in Fig. 2. When the radiator is constructed with sections of this type, the front wall 24 radiates 'this radiator.

The radiator shown in Fig. 4 is another modification in which the back plate'25 of each section is carried forward at the lower end, as in the radiator in Fig. 2, but extends upward without curvature. The front plate 24 extends upward also to the level of the upper end of the back plate thus providing an outlet opening in the top of'the radiator and maintaining the front of the radiator closed. As shown in the drawings, the inlet opening 2 is formed in the base diator communicates with a horizontally disposed grill 32 in the top of a shelf or sill 33* above the radiator. This particular structure is shown with five horizontal runs of tubing.

In the event that "the radiator is to be used for heating air brought into a room from out-of-doors, or from an air well in the wall, it may be constructed as shown in Fig. 5. In this structure the back plate 25 is curved forward at the top and is terminated at the bottom just below the lower run of the pipe 9 as in the modification shown in Fig. 3. The outlet opening 4 is provided in the forward face of the radiator near the top in the usual manner. For admitting air from the rear an inlet opening 33 is provided in the outer surface of the wall 1 at the bottom of the radiator. To form a streamline air passage from the inlet opening 33 into the radiator thelfro nt' plate 24 board 3' and the outlet opening of the raa the radiator shown in Fig. 8 is puttogether,

with the exception that no intermediate I in plates are placed within the sections.

, As shown in Fig. 7, the tubes 9 are passed through the tube-receiving openings 23 in the transverse plates 22, in such manner that the front and back plates form a continuous outer shell or cabinet for the radiator. After the transverse plates 22 have been mounted the structure be rigidly 398i n" ings :23, by connecting process.

Suitable end plat may be applied in eny convenient manner to enclose the bends the tubes 9 or the tube bends may simply be covered and hidden from view. The unitary structure may then be mounted in a recess in the wall of a room as shown.

After being thus mounted, the usual supply and return pipes may be connected to the tubes 9 and the plaster or other wall covering applied either directly to the ziront plates 52A- or supported on a suitable structure spaced from the plates 24. Tll8 appearance of the finished heating unit may be van - enhancedby applying a suitable beading or till \ radiator.

vmay be used in any border 35, that may be of polished metal or other suitable material, around the inlet and outlet openings.

As shown in Fig. l, the exposed edges of the transverse plates 22 constitute in themselves a decorative grill and prevent to a large extent, viewing of the interior of the if it is desirable, any well known type of decorative grill structure may be applied to the inlet and outlet openings in the same manner that such grills are now applied to air outlet openings for admitting heated air to a room from recessed or concealed radiators.

In Fig. l a covered front panel is applied to one modification of the invention, and in Fig. 8 an exposed radiating panel is shown on another modification, but it will be understood that either of these and other modifications may be utilized with either the exposed radiating front panel or with the recessed panel covered by the wall covering which is applied to the walls of the room. Any convenient number of runs of tubing modification. Also it will be understood by those skilled in the art to which this invention relates that various other modifications may be made in the structures embodying the invention without departing iromthe'ispirit and scope of the invention defined in the appended claims.
